HAIR-CLIPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 333.340, dated December29,1885.

Application filed May 6, 1885. Serial No. 164,568.

against a second toothed blade or plate,which is usually stationary.

The invention,while applicable to shearing purposes and to tonsorialuse, as in trimming or cutting the hair on the human head, is moreparticularly designed for horse-clipping pur- 7 poses, and it Will herebe described more especially with reference to such use.

In power-machines of this description the two toothed blades orplatesthat is, both the stationary and reciprocating plates haveheretofore had a fixed transverse relation to the handle by which themachine is manipulated over the surface to be clipped,and to the framewhich carries the gearing for reciprocating the one plate.

My invention consists in a swiveling connection of the stationarycutting-plate and certain connection with its gearing of thereciprocating plate, whereby both plates may be swiveled to occupydifferent transverse positions or angles relatively to the handle of themachine and frame or box which carries the gearing without interferingwith the motion of the latter, thereby giving increased facility formanipulating the machine, to adapt the cutters to work over differentparts or surfaces and in different directions as regards the out.

The invention likewise includes certain means for taking up the wear ofthe working parts and avoiding lost motion in the cutter, so as toinsure its perfect operation at all times.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 represents a longitudinal section of a power-machine, suitablefor clipping horses, embodying my invention; Fig. 2, a sectional View onthe line x w in Fig. 1 of the same in part.

(Model A is the handle by which the machine is manipulated over thelimbs or body of the animal, and B the box or frame which carries thetoothed cutting-plates O D and the gearing by which the reciprocatingtoothed cuttingplate D is operated.

E is the operating rotating shaft, arranged to pass longitudinallythrough the handle A, and which is connected withthe main or counterdriving-shaft by the usual spiral-spring coupling, G, to give thenecessary driving or working flexibility to the instrument, so far asits manipulation over the surfaces to be clipped is concerned; butinstead of said spring-coupling being rigidly or permanently attached tothe shafts which it connects it is loosely slipped over the end of eachor either shaft and engaged therewith by simply turning it and causingits end spirals to receive within them a stud, b, on the shaft. Thismode of engaging the spiral-spring coupling with its shaft or shafts notonly provides for the ready engagement and disengagement of saidcoupling, but also admits of either a right or left hand spring beingused to accommodate it to a main or counter driving-shaft rotatingeither to the right or to the left, thus adapting the implement to beworked from shafts moving in reverse directions, which will be found agreat convenience.

The operating-shaft E communicates the necessary reciprocating motion tothe toothed clipping-bar D by means of a bevel-wheel, 0, arranged toengage with a like wheel, d, on a spindle, H, that has its bearings inthe box or frame B. On the inner end of the spindle H is a crank, f,that serves, by its connection through a link or connecting rod or bar,9, with a lever, h, to give the necessary reciproeating motion to thebar or plate D. Such are the ordinary means of reciprocating thecutting-plate D, that is held to its bearing on the stationarycutting-plate O and guided in a straight line or course thereon in theusual or any suitable manner. Instead,however,of the IOO clipping barsor plates will give an enlarged versatility or flexibility to theimplement,and enable it to be worked over or applied to different partsof the animal with greater freedom, thus extending the manipulatingcapacity of theimplement,inasmuch as the clipping-plates -may be set towork at different angles relatively to the handle A and box or frame B.To provide for this swiveling adjustment of the plates 0 D, thestationary plate 0, on which the reciprocating plate D is fitted towork, is attached by a screw or other pivot, '11, in the same axial lineas the spindle H to the box or frame B. This admits of theclipping-plates being swiveled, as required, without interfering withthe gearing or operating devices of the reciprocating plate.

It is important that the cutting-teeth of the reciprocating plate Dshould at all times have a full stroke over the teeth of the stationaryplate 0, and as this is liable to be interfered with by lost motionconsequent on the wear of the reciprocating devices, I provide forincreasing, when necessary, the length of the stroke of the crank f byconnecting the bar 9 with it through a slot, 7c, and nut Z,- or suchadjustable connection maybe applied to either end of the bar g-that is,either to the crank and bar, as shown, or to the bar 9 and lever h-so asto give the necessary stroke to said lever.

Having thus fully described myinvention, I claim as new and desire tosecure by'Letters Patentsaid box or frame and handle of the implement,substantially as specified.

2. The combination of the operating-shaft E, the handle A, the box orframe B, the gears c d, the spindle H, the crank f, the connecting-rodg, the lever h, the reciprocating cutting-plate D, the stationarycutting-plate '0, and the pivot i, essentially as shown and scribed.

3. The combination, with the toothed eutting-plates O D, of the lever h,the crank f, having a slot, is, in it, the nut Z, and theconnecting-rodg, by which reciprocating mot-ion is given to the cutting-plate D,whereby lost motion may be taken up to secure the proper action of thecutters, substantially as specified.
